Finding Patterns in Geological Data
Finding Patterns in Geological Data
Scientists look for patterns in data to support theories. Geologists know that tremendous
forces build up as tectonic plates move against each other. Is there a direct connection
between plate movement and the location of mountain ranges, volcanoes, and earthquakes?
If so, how would this connection support the theory of plate tectonics?
Part I – Making Predictions
Based on your knowledge of plate tectonics, make a prediction to answer the following
questions;
1.
Where are earthquakes most likely to occur?
Prediction: ___________________________________________________________
___________________________________________________________________
___________________________________________________________________
2. Where are volcanoes most likely to occur?
Prediction: ___________________________________________________________
____________________________________________________________________
____________________________________________________________________
3. Where are mountain ranges most likely to occur?
Prediction: ___________________________________________________________
____________________________________________________________________

Part II – Using Data
Directions: Using the data table and latitude/longitude map provided work through the
following steps.
1. Label 00 Latitude as the equator and label 00 longitude as the Prime Meridian.
2. Outline the continents in a dark green pencil crayon and shade the interior of the
continents a lighter green. Then shade the oceans blue.
3. On the world place a small black circle at the location of each earthquake listed in
Table 1.
4. Place a small red triangle on your world map at the location of each volcano listed on
Table 2
5. Use a third colour to mark the location of the following mountain ranges; Rockies,
Urals, and Appalachians. You will have to use an Atlas or the internet to help you.
6. Once your world map data has been plotted, compare it to your Plate Boundaries Map
and see if you can find any pattern in the locations of earthquakes, volcanoes or
mountain ranges.
7. Go back and look at your predictions. Do the patterns you found support, partly
support, or not support your predictions? Write a short paragraph that explains
what you have learned in this investigation.
